Redirect with apply_coupon

[ckarkowsky]

Hello,

I want to be able to email customers a link that adds a product to the cart with a certain quantity, and apply a promocode, like this:

http://xyz.com/purchase/?add-to-cart=35168&quantity=2&apply_coupon=amnesty17

If you click on this directly when you are not on the site, it will redirect (in my case) back to the purchase page. I would like to stay on the cart page (as defined by wc_get_cart_url()). There is also a setting in WC where you set to redirect to the cart page when a product is added to the cart.

Here is the function within add_to_cart_action

// If we added the product to the cart we can now optionally do a redirect.
		if ( $was_added_to_cart && wc_notice_count( 'error' ) === 0 ) {
			// If has custom URL redirect there
			if ( $url = apply_filters( 'woocommerce_add_to_cart_redirect', $url ) ) {
				wp_safe_redirect( $url );
				exit;
			} elseif ( get_option( 'woocommerce_cart_redirect_after_add' ) === 'yes' ) {
				wp_safe_redirect( wc_get_cart_url() );
				exit;
			}
		}

The coupon plugin however seems to ignore this here in coupon_by_url()

//Redirect to page without autocoupon query args
		if ( $must_redirect ) {
			$requested_url  = is_ssl() ? 'https://' : 'http://';
			$requested_url .= $_SERVER['HTTP_HOST'];		   
			$requested_url .= $_SERVER['REQUEST_URI'];

			wp_safe_redirect( remove_query_arg( array( 'apply_coupon', 'add-to-cart' ), ( $requested_url ) ) );
			exit;
		}

If i remove the coupon code, the link works fine, and stays on the cart page.

Is there a way to include the apply_coupon and honor the redirection set by WC?

Thanks!

Chris

There has been a lot of struggle with add-to-cart in combination with apply_coupon.

Best option is to use this little plugin: https://wordpress.org/plugins/soft79-cart-links-for-woocommerce/

and replace ?add-to-cart=35168&quantity=2 with ?fill_cart=2×35168
